T (tZZ whom it may concern:

Be it known that I, CHARLES J. WALz, a citizen of the United States, and a resident of the borough of Manhattan, in thecityand State of New York, have invented a new and useful Improvement in Air-Forcing Devices for Atomizers,of which the following is a specification.

My invention relates to an air-forcing del o vice for atomizers in which a piston is worked in a cylinder as the door is opened and closed for spraying a fluid into the surrounding atmosphere.

A practical embodiment of my invention is r 5 represented in the accompanying drawings,

in which- Figure 1 is a view of the device in side elevation applied to a full-swing door. Fig. 2 is a top plan View of the same, the device being shown in full lines in the position which it assumes when the door is closed and in dotted lines in two different positions which it assumes when the door is opened in opposite directions. Fig. 3 is aview of the device in side elevation applied to a half-swing door; and Fig. 4c is a top plan view of the device, showing it in full lines in the position which it assumes when the door is closed and in dotted lines in the positionswhichit as: sumes when the door is opened to two different positions.

The door is denoted by a, and it may be of any well-known or approved construction. It is hinged to the frame at b. The door rep- 3 5 resentedin Figs. 1 and 2 is a full-swing door and in Figs. 3 and 4a half-swing door, a stock a being arranged to engage the free edge of the door to prevent its swinging beyond a line with the frame in one direction.

The cylinder (Z of the air-forcing device is supplied with a piston of well-known form operated by a piston-rod 6, one end of which is fitted to receive a pintle f, uprising from the base g of a bracket secured to one face of the door adjacent to its hinged end.

The outer end of the cylinder cl is supported by a downwardly-turned free end of a sprin gactuated arm h, which passes through a socket t', fixed to the end of thecylinder, the lower end of the said arm projecting through the bottom of the socket and being there provided Serial no. 51,968. on model.)

with some means for retaining the arm in the socket-such, for instance, as a keyj. The outer end of the cylinder is further provided with an air-escape nozzle 7t, to which may be connected an air-tube Z,as shown in Figs. 3 and 4, leading to some suitable atomizer. (Not shown herein.)

The spring-actuated arm 7L is hinged on a bracket m, fixed to the door-frame. A spring at normally holds the arm h in engagement with the top of the door-frame.

WVhen the air-forcing device is used in connection with a full-swing door, the parts are so secured to the door and frame that the cylinder d will be free to swing beneath the top of the frame, while the arm 72, will be located in the same horizontal plane as the said top of the frame. In this construction when the door is opened in one direction the pis- 7o ton-rod and cylinder are positively drawn apart as the piston and arm swing on their adjacent hinge. When the door is allowed to close, the movement of the piston toward the outer end of the cylinder will force the air through the nozzle It. When the door is swung in the opposite direction, the piston will be drawn toward the inner end of the cylinder, the outer end of the cylinder at the same time; swinging on its hinge connection withthe arm h, permitting the cylinder to swingbeneath the top of the door-frame. In this instance also when .the door is permitted to close the piston will be forced toward the outer end of the cylinder, thus forcing the air out through the nozzle 75.

In the form shown in Figs. 3 and 4, Where the device is to be used in connection with a half-swing door, the parts are secured in such position on the door and frame that the cylinder, as well as the arm, will be located in the horizontal plane of the top of the doorframe. In this instance the door may be opened until the piston reaches the limit of its inward movement without swinging the 95 spring-actuated arm h. A further outward movement of the door will cause the arm h to also swing outwardly on its hinge. As the door is swung inwardly from the limit of its outward movement the cylinder and arm will I00 first be put into engagement with the top of the door-frame and the piston be forced toward the outer end of the cylinder for ejecting the air through the nozzle 70.

It will thus be seen that the device, as above described, may be used to equal advantage with full-swing and half-swing doors without changing the structure of the device in any particular.

It is evident that changes might be resorted to in the form, construction, and arrangement of the severalparts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein setforth; but

What I claim is 1. In an air-forcing device for atomizers, the combination with a door and its frame, of a swinging arm hinged to the frame, a cylinder and its piston, the cylinder-piston being hinged to the door and the cylinder being pivoted to the swinging arm, substantially as set forth.

2. In an air-forcing device for atomizers, the combination with a door and its frame, of a swinging arm hinged to the frame, a cylinder and its piston, the cylinder-piston being pivotally secured to the door and the said cyl inder being at its opposite ends pivoted to and supported by the swinging arm, substantially as set forth.

3. In an air-forcing device for atoinizers, the combination with a door and its frame, of a spring-actuated swinging arm normally in engagement with the frame, a cylinder and its piston, the cylinder-piston being pivoted to the door, the said cylinder being at its opposite end pivoted to and supported by the springactuated arm, substantially as set forth.

4:. In an air-forcing device for atomizers, the combination with a door and its frame, a bracket secured to the door, a swinging arm hinged to the door-frame, a cylinder and its piston, the cylinder-piston being hinged to said bracket, the said cylinder being pivoted to and supported by the swinging arm at its outer end, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in pres ence of two Witnesses, this 6th day of March, 1901.
